Nb2CTx MXene Phase Powder
Nb₂CTₓ MXene Phase Powder is a two-dimensional niobium-based carbide material, belonging to the MXene family, produced by selectively etching the aluminum layer from its precursor Nb₂AlC MAX phase. The resulting layered structure is surface-functionalized with groups such as -O, -OH, and -F (denoted as Tₓ), which grant the material hydrophilicity, tunable electronic properties, and enhanced chemical reactivity. Nb₂CTₓ exhibits good electrical conductivity, notable chemical stability, and promising electrochemical activity. It is widely studied for applications in advanced energy storage systems—including lithium-ion and sodium-ion batteries—as well as in electromagnetic interference (EMI) shielding, gas sensing, and electrocatalysis, benefiting from the unique properties of niobium such as high redox activity and corrosion resistance.

Nb2CTx MXene Phase Powder Description
Nb₂CTₓ MXene Phase Powder is a two-dimensional transition metal carbide nanomaterial synthesized through the selective etching of aluminum from the Nb₂AlC MAX phase precursor, typically using hydrofluoric acid or fluoride-containing etchants. This process yields accordion-like, multilayered particles terminated with surface functional groups (Tₓ), such as -O, -OH, and -F, which critically influence its hydrophilicity, surface charge, and electrochemical behavior. Characterized by its niobium-rich composition, this MXene exhibits distinct advantages including good metallic electrical conductivity, excellent chemical and electrochemical stability, and a high concentration of active sites suitable for redox reactions. Its layered architecture provides a large specific surface area and interlayer spacing conducive to ion intercalation. Consequently, Nb₂CTₓ is a highly promising material for advanced energy storage applications—notably as an electrode material in lithium-ion, sodium-ion, and potassium-ion batteries, as well as in supercapacitors. Beyond energy storage, it demonstrates significant potential in electromagnetic interference (EMI) shielding, photocatalysis, gas sensing, and reinforcement for composite materials, leveraging the inherent properties of niobium such as corrosion resistance and redox activity.
